Don't understand the chassis number so it might be worth a trip to a friendly Mercedes dealer.

The engine in the 230SL was a bored out version of the M127 from the 220SEs. The engine at the same time was given bigger valves for breathing, revised timing and a higher compression ratio. The 2 plunger fuel injection was replaced by a six plunger pump.

I would imagine your vehicle may have been built around 1962 and sold to a member of the public after they had finished with it. Which was not uncommon back then as I had a W123 200 Mercedes which was built in 1978 but had the later 1980 M102 engine fitted.
